HENRY K. HESS, OF SYRAOUSEVNEl/V YORK.

STEAM-GENERATOR.

SPECIFICATION forming part of Letters Patent No. 582,351, dated May 11,189'?. Application liled June 16, 1896. Serial No. 595,770. (No model.)

To all whom t may concern:

Be it known that I, HENRY K. Hass, of Syracuse, in the county ofOnondaga, in the State of New York, have invented new and usefulImprovements in SteamGenerators, of which the following, taken inconnection with the accompanying drawing, is a full, clear, and exactdescription.

My invention relates to improvements in generators for steam or hotwater, and has for its object the production of a device which producesa maximum amount of steam at a minimum cost of fuel; and to this end itconsists, essentially, in the general construction -and arrangement ofthe component parts of the generator, all as hereinafter fullydescribed, and pointed out in the claims.

In describing this invention reference is had to the accompanyingdrawing, forming a part of this specification, in which like lettersindicate corresponding parts.

The drawing is a sectional view, partly in elevation, of my improvedgenerator.

As is well known a great amount of heat is produced upon the explosionof gases, and my improved generator is of such construction that heatgenerated in this manner is utilized to raise the temperature of acirculating fluid and, if desired, to generate steam.

A represents a water-containing receptacle, B a chamberfor heating theWater in said receptacle, and O an explosion -chamber, which receivesgas,`vaporized oil, or similar fuel, communicates with the chamber B,and is surrounded by a water-containing chamber O', preferably suppliedby a feed-water pipe O2.

A conduit c preferably connects the chambers B C, and a valve D of anydesirable construction is movable in a valve-chamber opening from saidconduit and operates to control the passage of the gas through saidconduit.

Oonduits A' B conduct the hot water or steam and the exploded gas fromthe receptacle A and the chamber B and discharge the same into a conduitA2, which conveys the hot water or steam and the exploded gas to anydesired locality for utilization. An automatically-operating valve B2 inthe conduit B prevents return of the exploded gas, the., into thechamber B.-

A suitable conduit c discharges gas within the chamber C, which ispreferably provided with'an automatically-operating vent-valve C2. Aconduit c2 permits the escape of the exploded gas from said chamber.Valves D D2, of any desirable construction, regulate the passage of thegas and air through said conduits, and an igniter consisting ofnormally-separated terminals c3 c4 produces the spark for exploding saidgas and air.

The valves D D D2 are operated bysuitable means, here illustrated assprings cl d d2, a shaft D3, driven by any desirable power-transmittingmechanism, (unnecessary to herein illustrate and describe,) and suitableconnections between said shaft and valves. The terminals c3 c4 of theigniter are contacted with each other by suitable connections betweensaid shaft Dgand one of the terminals, which is movable toward and awayfrom the other terminal. The gas mixed with a suitable amount of air isforced through the conduit c by any desirable means, as a pump D4, whichis connected to said conduit and a gas-supply conduit c5, and isprovided with a piston connected to suitable driving means, as the shaftD2. If desired, however, the air may be fed to the chamber O in the samemanner as the gas by a separate conduit, and suitable means for feedingthe air through said conduit and controlling its discharge therefrom.

In the operation of myinvention the valve D closes the passage betweenthe chambers B O, gas and air are fed within the chamber O, the valves DD2 shut off the passage of the gas and air, the valve D opens thecommunication between the chambers B C, and the igniter then explodesthe gas and air, which is free to expand into the chamber B. After theexplosion of the gas the valve D prevents communication between thechambers B O, the valve D2 temporarily permits the disch-arge of theexploded gas from the chamber O and then prevents said discharge, andthe valve D permits the entrance of additional-gas within theexplosion-chamber C. The heat generated by .the explosion of the gasraises the temperature of the fluid within the receptacle A and thechamber O', and the valve B2 permits the escape of the exploded IOOgases from the chamberB when the pressure within said chamber issufficient to operate the valve.

The operation of my invention will now be readily understood uponreference to the foregoing description and the accompanying drawing, andit will be particularly noted. that I do not herein specifically limitmyself to the detail construction and arrangement of the component partsof my generator.

Having thus fully described my invention, what I claim, as new, anddesire to secure by Letters Patent, is-

l.` In agenerator for steam or hot water, the combination of awater-containing receptacle, a heating-chamber for heating the water inthe receptacle,` an explosion-chamber comm unicating with theheating-chamber for discharging the exploded gas thereinto, and a valvefor controlling the passage betweensaid chambers, substantially as andfor thepurpose described.

2. In a generator for steam or hot water, the combination of awater-containin g receptacle, a heating-chamber for heating the water inthe receptacle, an explosion-chamber communicatin g with theheating-chamber for discharging the exploded gas thereinto, a valve forcontrolling the passage between said chambers, anda water-containingchamber surrounding the chamber for the valve,4 substantially as and forthe purpose specified.

3. In a generator for steam or hot water, the combination of awater-containin g receptacle, a heating-chamber for heating the water inthe receptacle, a gas-explosion chamber communicating with theheating-chamber for discharging the exploded gas thereinto, avalve forpermitting the discharge of the exploded gas from the explosion-chamberand preventing return of the discharged gas, and automatically-operatingmeans for actuating the valve, substantially as and for the purpose setforth.

et.
